Detective Marlowe arrived at Blackwood Manor after midnight precisely alone. The butler opened the heavy door, trembling visibly from fear. Inside, Lord Harrington lay dead upon bloodstained expensive Persian rug. No obvious weapon was present near the body anywhere tonight. Three guests lingered upstairs, each hiding terrible secrets silently tonight. Rain hammered windows while Marlowe examined the cold corpse carefully. Someone closed second-floor shutters immediately after lightning flashed brightly outside. The clock struck one, though previously stopped last Tuesday mysteriously.
